Im getting two failures: 1)Your #navbar should have exactly one header element within it. 2) Each .nav-link should have an href attribute that links to its corrosponding .main-section. I don’t see what i am doing wrong.

<nav id="navbar">
  <header>JS Documentation</header>
  <ul>
    <li><a class="nav-link" href="#introduction">Introduction</a></li>
    <div id='divider'></div>
    <li><a class="nav-link" href="#what you should already know">What you should already know</a></li>

  <p>JavaScript is a cross-platform, object-oriented scripting language. It is a small and lightweight language. Inside a host environment (for example, a web browser), JavaScript can be connected to the objects of its environment to provide programmatic control over them.</p>
  <p>JavaScript contains a standard library of objects, such as Array, Date, and Math, and a core set of language elements such as operators, control structures, and statements. Core JavaScript can be extended for a variety of purposes by supplementing it with additional objects.</p>
  <li>Client-side JavaScript extends the core language by supplying objects to control a browser and its Document Object Model (DOM). For example, client-side extensions allow an application to place elements on an HTML form and respond to user events such as mouse clicks, form input, and page navigation.</li>
  <li>Server-side JavaScript extends the core language by supplying objects relevant to running JavaScript on a server. For example, server-side extensions allow an application to communicate with a database, provide continuity of information from one invocation to another of the application, or perform file manipulations on a server.
  </li>

<section class="main-section" id="JavaScript_and_Java">  
  <header><h1>JavaScript and Java</h1></header>
   
  <p>JavaScript and Java are similar in some ways but fundamentally different in some others. The JavaScript language resembles Java but does not have Java's static typing and strong type checking. JavaScript follows most Java expression syntax, naming conventions and basic control-flow constructs which was the reason why it was renamed from LiveScript to JavaScript.</p>
  <p>In contrast to Java's compile-time system of classes built by declarations, JavaScript supports a runtime system based on a small number of data types representing numeric, Boolean, and string values. JavaScript has a prototype-based object model instead of the more common class-based object model. The prototype-based model provides dynamic inheritance; that is, what is inherited can vary for individual objects. JavaScript also supports functions without any special declarative requirements. Functions can be properties of objects, executing as loosely typed methods.</p>
  <p>JavaScript is a very free-form language compared to Java. You do not have to declare all variables, classes, and methods. You do not have to be concerned with whether methods are public, private, or protected, and you do not have to implement interfaces. Variables, parameters, and function return types are not explicitly typed.</p>

<section class="main-section" id="Hello_World">  
  <header><h1>Hello World</h1></header>
  
    
  <p>To get started with writing JavaScript, open the Scratchpad and write your first "Hello world" JavaScript code:
</p>
<p>Select the code in the pad and hit Ctrl+R to watch it unfold in your browser!</p>
<code>function greetMe(yourName) { alert("Hello " + yourName); }
greetMe("World");</code>
</section>

<section class="main-section" id="Variables">  
  <header><h1>Variables</h1></header>
   
  <p>You use variables as symbolic names for values in your application. The names of variables, called identifiers, conform to certain rules.</p>
  <p>A JavaScript identifier must start with a letter, underscore (_), or dollar sign ($); subsequent characters can also be digits (0-9). Because JavaScript is case sensitive, letters include the characters "A" through "Z" (uppercase) and the characters "a" through "z" (lowercase).</p>

  <code>With the keyword var. For example,

<code>By simply assigning it a value. For example,

<code>This always declares a global variable. It generates a strict JavaScript warning. You shouldn't use this variant.

And apparently i don’t know how to copy and paste my code. :frowning:

I figured the first one. My was misspelled

I’ve edited your post for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.

See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (').

The href values should match the section id values, including how you replace spaces with underscores.
